Anaphylaxis is a severe and life-threatening allergic reaction that requires immediate treatment. Epinephrine, also known as adrenaline, is the first-line treatment for anaphylaxis. However, the intramuscular dose of Epinephrine can vary based on the severity of the reaction. Option A and D are incorrect because they are too low to effectively treat anaphylaxis. Option C is also incorrect because it is too high and can potentially cause harmful side effects. The correct answer, B, falls within the recommended range of 0.3-0.5mg, which is enough to reverse the symptoms and prevent life-threatening complications.
